And im looking at buying a lens with a better zoom .
im looking at the 55-200mm how far will it zoom surrounded by feet?


Answers:    You're looking at zoom within the wrong way. A lens can focus to infinity, so they'll adjectives zoom to infinity.

A 50mm lens is a standard view. 55mm is 110% of majority, of 1.1X zoom. Not much. A 200mm zoom is 4X normal belief. (A typical set of binoculars magnifies 8X, for comparison.)

But there's a confine. Your D40 has an statue sensor that's smaller than a standard 35mm film frame, so similes seen through the lens appear to be magnified 1.5X. Multiply this crop factor (or focal factor or multiplication factor) times your lens focal lenth to seize the lens' apparent size within your camera.

1.5 times 200mm equals 300mm, or 6X the normal display.
